Abstract
The present invention relates to a processing method for disinfecting transgenic seeds of soybeans, which belongs to the technical field of biology and modern agriculture. The present invention controls temperature within 2 DEG C to 6 DEG C through using a method of controlling the temperature, and disinfecting liquid is added and disinfecting time is prolonged to 50 to 70 minutes; thus, various microbes can be killed. The present invention has the substantive characteristics and the remarkable progress; the present invention solves the difficulty that the contamination is easy to cause because the seeds are not thoroughly disinfected, the seed germinating capacity of the soybeans is influenced because of long disinfecting time, and therefore, germinability is weakened so as to reduce the contamination of the seeds of soybeans and keep high germination rate and strong germinability. Compared with a method that the seeds which are soaked by 0.1% of HgCl#-[2] under normal temperature for 15 minutes or are soaked by saturated bleaching powder solution for 25 minutes, the present invention has the advantages of thorough disinfection of the seeds, strong germinability and robust growth.
Description
Technical field
The present invention relates to a kind of seed disinfection processing method, particularly a kind of soybean transgene seed disinfection processing method belongs to biotechnology and modern agricultural technology field.
Background technology
Along with development of biology, genetically modified crops gradually move towards market, soybean is one of them important crop.Seed disinfection is first link of work in soyabean tissue cultivates, and pathogen contamination is the big obstacle that sterile tissue is cultivated.Find that by literature search Gansu science tech publishing house published in 1996, " practical plant tissue culture technique study course " P39 page or leaf of chief editors such as Cao Ziyi: conventional method is generally used 0.1%HgCl
2Solution soaking 15 minutes or saturated Eusol soaked 25 minutes.But usually sterilization is not thorough at work, and pollution happens occasionally, and causes the accuracy of the waste and the influence experiment of test material, if the time soaks long then seed sprouting is caused infringement, percentage of seedgermination is descended, and germination vigor weakens.
Summary of the invention
The objective of the invention is to overcome the deficiency and the defective of existing sterilization method, a kind of soybean transgene seed disinfection processing method is provided, make the soya seeds sterilization thoroughly, pollution-free, do not influence seed germination again, the seedling robust growth, it is many to reach soybean group training indefinite bud, the effect of fast growth.The present invention is achieved through the following technical solutions: the present invention mainly adopts the mode of control temperature, temperature is controlled at 2 ℃～6 ℃, after adding thimerosal, and prolong disinfecting time to 50～70 minute, thereby kill various microorganisms, can guarantee that the soya seeds pollution rate drops to 0.1%-0.7%, and do not influence the normal sprouting of soya seeds, germination rate remains on 97%-99%, and germination vigor is strong.
Below step of the present invention is further described:
(1) soya seeds, 75% alcohol, 0.1% mercury chloride or saturated Eusol remain on 2 ℃～6 ℃.
(2) select kind of a skin and do not have breakage, no scab seed cleans up through running water, blocked down in alcohol-pickled 30 seconds with 2 ℃～6 ℃ 75% again and do.
(3) add 2 ℃～6 ℃ 0.1% mercury chloride or saturated Eusol and soak, and remained in the scope of 2 ℃～6 ℃ of temperature 50～70 minutes.
(4) under aseptic technique, add to be connected on the MS medium behind 2 ℃～6 ℃ aseptic water washings 3～8 times and sprout, through cultivating the seedling that obtained sprouting in 5～7 days.
The present invention has substantive distinguishing features and marked improvement, the invention solves the pollution that seed does not thoroughly cause owing to sterilization, and owing to disinfecting time length influences the soya seeds germination rate, weaken the difficult point of germination vigor, the soya seeds pollution rate is descended, and keep high germination rate and strong germination vigour, and select 0.1%HgCl below the normal temperature for use
2Solution soaking 15 minutes or saturated Eusol soak to be compared in 25 minutes, and seed disinfection is thorough, and germination rate rises germination vigor enhancing, robust growth.
